We notice that the upper trapezoid is symmetric to the lower one & the line of symmetry should be a horizontal line (mirror line) where any point of the upper vertices should be at equal distance (perpendicular) with the related vertices of the lower one from this horizontal line:
Note that QQ" =4 units, Hence the line of symmetry is the perpendicular to QQ' at 2 units
Answer: e. .0950
Step-by-step explanation:
Let X be the number of people that can be cure from disease.
Since each people independently has a 40% chance of contracting the disease.
So , 
A hospital has the capacity to handle at most 8 cases of the disease.
Binomial distribution formula : 
Then , the probability that the hospital’s capacity will be exceeded
![P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]](https://tex.z-dn.net/?f=P%28X%3E8%29%3D1-P%28X%5Cleq8%29%5C%5C%5C%5C%3D1-0.905%5C%20%5C%20%5B%5Ctext%7BUsing%20Binomial%20distribution%20table%20for%20n%3D15%20%2C%20x%3D8%20and%20p%3D0.4.%7D%5D)

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.
Thus , the correct option is e. .0950.

Answer:
7%
Step-by-step explanation:
Let x represent the percentage of water in the mix. The amount of water in the mix is ...
5%·120 +10%·80 = x·(120 +80)
14/200 = x = 7% . . . . . . . . . . . . . . simplify, divide by 200
The percentage of water in the mixture is 7%.
